Products/Services for Filters Active
Active filters are electronic filers that use active components such as voltage amplifiers or operational amplifiers. The amplifier shapes and stabilizes the behavior of the filter, and serves as a buffer interface to the driven component. Search by Specification | Learn More about Active Filters
Active low pass filters pass signals from low frequencies and reject signals from high frequencies. Search by Specification | Learn More about Active Low Pass Filters
Active band pass filters are used to attenuate frequencies below and above a range of frequencies (i.e., the bandwidth or passband of the filter). Learn More about Active Band Pass Filters
Active band reject filters are tuned circuits that prevent the passage of signals within a specified band of frequencies. These devices are also known as bandstop or notch filters. Learn More about Active Band Reject Filters
Active high pass filters pass signals from high frequencies and reject signals from low frequencies. Learn More about Active High Pass Filters
RF band pass filters are active or passive circuits that pass signals from a specific frequency band and reject signals from out-of-band frequencies. Surface acoustic wave (SAW) filters, crystal filters, and cavity filters are types of band pass filters. Search by Specification | Learn More about RF Band Pass Filters
RF filters and microwave filters are devices that pass or reject signals by frequency. Basic types include bandpass filters, band reject filters, low pass filters, and high pass filters. Search by Specification | Learn More about RF Filters and Microwave Filters
...filters or line/load reactors. There are two choices for filter type: passive and active.

Search by Specification | Learn More about Harmonic Filters
IC electronic filters are frequency-selective circuits that consist of devices such resistors, capacitors, inductors, transistors, or operational amplifiers coupled with reactive components. Search by Specification | Learn More about IC Electronic Filters
Electromagnetic (EMI) filters and radio frequency interference (RFI) filters purify signals by attenuating the high-frequency RFI (typically 150kHz and up) and passing the low frequency EMI. Search by Specification | Learn More about EMI Filters and RFI Filters
Industrial air filters reduce the number of particles in the air that passes through them. Search by Specification | Learn More about Industrial Air Filters
RF low pass filters pass signals from low frequencies and reject signals from high frequencies. Search by Specification | Learn More about RF Low Pass Filters
...of power types of power factor correction (PFC) products: active and passive. Active PFC circuits use switch-mode converter techniques and are designed to compensate for distortion as well as displacement on the input current waveform. Active PFC circuits...

Product News for Filters Active
Active Tracking® Filters
Low voltage/high frequency noise is caused by everyday events such as turning on machinery, motors, or equipment. Although noise is less dramatic than high voltage transients, the long term effects of these frequent disturbances can be as damaging. Filtering systems such as SolaHD Active Tracking Filters provide clean AC power by eliminating lower voltage noise. (read more)
